Practical work 3.

This is a crosswords puzzle with words to unscramble. I would add translations of each word in your students' mother tongue or definitions/explanations to make it easier.

Practical work 4.

This worksheet in colour can be used to teach a few words related to computers and ICT technology. Students have to match the words with the pictures. It is an easy but useful activity.

Match the words with the pictures.

Practical lesson 4 Software. Operating systems.

Trackball is an inverted functional mechanical (ball) mouse. 2) Plotter, Plotter - a device for the automatic drawing with accurate drawings, schemes, complex drawings, maps and other graphical information. Plotters draw the image with the pen (writing block). 3) The touchpad, touchpad - pointing input device used mostly in laptops. Like other pointing devices, the touchpad is usually used to control the "index" by moving a finger across the surface of the device. 4) Graphic tablet - a device for inputting images of the hand directly into the computer. It consists of a pen and a flat plate, pressure-sensitive pen or proximity. Also, a special mouse can be attached.
